It has been mentioned previously on this forum that if you change your billing date, you can end up with two bills to pay in the same month. Hence, I have always understood that as being that you can bring a future billing date forward, but not defer it. 

Unfortunately, I cannot test it as I am on PAYG ! 😀

@Oxonian 

You need to change your billing date 5-7 days before your bill is due to avoid 2 bills.

Personally I would give it a lot longer than that. (Particularly with the recent issues with CS and the systems!)

Payment date and billing date | Account and Billing | Help & Support | O2

But you explanation if far clearer ! 👍
